Essential Question
How do I
conduct and
experiment?
1. What is the
Scientific Method
it is an organized way
in figuring something
out.
2. What are the 5 steps of the
Scientific Method
1. Ask a question.
2. Form a hypothesis.
3. Design and conduct an experiment.
4. Analyze the results of the experiment.
5. Draw a conclusion.

Why is the Scientific
Method important?
Because when the scientific
method is used to solve a
problem. The procedure can
repeated by anyone and verify the
result/s.
4. What are the parts of
an Experiment?
Independent variable ( IV )
Dependent variable ( DV )
Control group
Experimental group
Independent variable (IV)
is the factor that you change
in the experiment.
Dependent variable ( DV ) is the
factor that we measure. It is the
result of the independent variable.
Control group is the one that
remains the same throughout
the experiment.
Experimental group is the
one that you manipulate or
change in the experiment.
Copy and answer the following
Questions in your Notebook.
1.What was tested in Mr. Koning’s experiment?
2. Why was Jacob’s suggestion regarding the experiment
not accepted by Mr. Koning?
3. How many Independent variable (IV) should there be
in an experiment?
4. What was the independent variable in the experiment?
5. What was the dependent variable or measured data
(DV) in the experiment?
6. What were the control variables ( CV)?

1.What was tested in Mr. Koning’s
experiment?
The rate of plant growth.
2. Why was Jacob’s suggestion regarding the
experiment not accepted by Mr. Koning?
Because Jacob was changing so many variables.
3. How many Independent variable (IV)
should there be in an experiment?
One variable only.
4. What was the independent variable in the
experiment?
Amount of water.
5. What was the dependent variable or
measured data (DV) in the experiment?
Plant growth rate measured in centimeters.
6. What were the control variables ( CV)?
Amount of sunlight, type plant, soil, humidity, temperature,
and location.
